in \(P_{\theta _0}^{(n)}\) -probability. General theory for posterior contraction rates in nonparametric Bayes was developed in the seminal work [1]} by verifying the prior mass and entropy conditions; see also [2]} for a similar result. The past two decades have seen a surge of interest in establishing posterior contraction rates under a variety of models and prior distributions [3]}, [4]}, [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}. We refer to Section 3.3 in [15]} for an excellent review.
